The devotee engages to the best of his ability into the play of life, fulfilling his role on this earth as student, employee, husband, wife, parent, neighbor, and community servant. But at the heart of the devotee is a burning desire for the Lord.
Thoughts are the medium through which the ego, the limited self, appears and paves the way for all our likes and dislikes, pleasure and pain.
There is no end to craving. Hence, contentment alone is the best way to happiness. Stay content.
